The adrenal cortex is a dynamic organ that undergoes self-renewal. In the mouse it is divided into two concentric layers, the outer zona glomerulosa (ZG) and the inner zona fasciculata (ZF), that secrete aldosterone and corticosterone, respectively. Capsular and subcapsular stem/progenitor cells differentiate and migrate in a centripetal fashion to repopulate the gland until they reach the juxtamedullary region where they undergo senescence and apoptosis. Cell fate mapping stu...

Adrenocortical carcinoma (ACC) is a rare malignancy with limited treatment options and a heterogenous prognosis. The histological diagnosis of ACC is complex and there is increasing interest in identifying and validating new immunohistochemical markers. Delta-like non-canonical Notch ligand 1 (DLK1) is a cleavable single-pass transmembrane protein. In humans, DLK1 is present in many tissues during foetal development, is restricted to progenitor/stem cells in a few adult tissue...
